Matthew 5:17-20 New American Standard Bible (NASB)
17 “Do not think that I came to abolish the Law or the Prophets; I did not come to abolish but to fulfill. 18 For truly I say to you, until heaven and earth pass away, not [a]the smallest letter or stroke shall pass from the Law until all is accomplished. 19 Whoever then annuls one of the least of these commandments, and teaches [b]others to do the same, shall be called least in the kingdom of heaven; but whoever [c]keeps and teaches them, he shall be called great in the kingdom of heaven.
20 “For I say to you that unless your righteousness surpasses that of the scribes and Pharisees, you will not enter the kingdom of heaven.
Matthew 5:17-20 Young's Literal Translation (YLT)
17 `Do not suppose that I came to throw down the law or the prophets -- I did not come to throw down, but to fulfill;
18 for, verily I say to you, till that the heaven and the earth may pass away, one iota or one tittle may not pass away from the law, till that all may come to pass.
19 `Whoever therefore may loose one of these commands -- the least -- and may teach men so, least he shall be called in the reign of the heavens, but whoever may do and may teach [them], he shall be called great in the reign of the heavens.
20 `For I say to you, that if your righteousness may not abound above that of the scribes and Pharisees, ye may not enter to the reign of the heavens.
